Three inverter motor controlling system
1. Three inverter motor controlling system:
Programmable controller control the main motor, rewinding and unwinding motor, the speeding and decelerating synchronously to ensure the same linear speed and stable film tension of rewinding and unwinding traction during the printing process and auto roll-changing. Set the tension value of the rewinding and unwinding traction by adjusting the precision reducing valve, and make it closed loop controlling with potentiometer and inverter motor. The advantage of the floating roller is that it can buffer the fluctuation of the film tension and ensure the registration accurate.
2. The feature of three inverter motor controlling: Less rewinding waste, better registration stability
1):Save much material, ink, solvent and power when the capacity is huge.
2):Rewinding speed 120m/min, rewinding waste 20m
3:Save ink, solvent, power 10%,,reduce the cost largely.
3,The comparation on the rewinding waste of three inverter motor controlling and magnetic powder auto tension controlling:
Magnetic powder auto tension: Rewinding speed 120m/min, rewinding waste 80m.
Three inverter motor controlling:Rewinding speed 120m/min, waste 20m.
